ENGINEERING PROLIFERATION AND TEXTURE DURING FRUITCHIPS VACUUM FRYING

摘要

Expansion and development as well as hard and crunchy fried products are characteristics preferred by consumers. To produce the expansion and texture of fried products to suit the tastes of consumers need to control and observe the process conditionsand the characteristics of the raw material change during the frying process. During the frying process volume change (expansion and contraction) and changes in texture (hard and crunchy) in foodstuffs. Volume and texture changes thought to be caused byevaporation of water and decreased levels of starch in solids. This research aims to develop a model of changes in volume and texture of the fruit during vacuum frying caused by a decrease in water content and starch content. Samples were jackfruit friedin a vacuum at a temperature of 70 - 100 °C; old frying pan 15-60 minutes and vacuum pressure 80-90 kPa. Parameters measured were the volume, texture, water content and starch content of samples before and after frying. The results showed that the model developed can be used with either to predict changes in the volume and texture of the product during the frying process in a vacuum.
